overview

Features

1. Hardening treatment of the parts surface: with longer operating life and excellent anti-wear properties

2. Simple structure: greatly minimize the chances of structural failure, convenient operation.

3. Take care of both the drilling wear life and drilling efficiency.

Advantages

* Long service life: abrasive ratio of cemented carbide is 10-20 times more than similar products, so the service life is greatly extended.

* High drilling efficiency: cemented carbide is of high hardness and good abrasion resistance. The drilling bit always keep sharps, thus largely increase the drilling speed.

* Wide application: The drilling bit is applicable for drilling the medium and hard strata, like carbonate rock, limestone, chalk rock, clay rock, siltstone, sandstone, etc.

* Because of fast drilling speed and long service life, the tripping times is less, and the drilling cost is greatly reduced, and it has superior cost performance ratio.
